How to change default elasticsearch password in docker-compose?

15,840

Starting from 6.0 elasticsearch docker images has the ability to configure the password using the following environment variable - ELASTIC_PASSWORD.
For example:
docker run -e ELASTIC_PASSWORD=MagicWord docker.elastic.co/elasticsearch/elasticsearch-platinum:6.1.3
See: https://www.elastic.co/guide/en/elasticsearch/reference/6.1/docker.html

    Elasticsearch's official docker image documentation provides this docker-compose.yml example:

    version: '2'
    services:
      elasticsearch1:
        image: docker.elastic.co/elasticsearch/elasticsearch:5.6.3
        container_name: elasticsearch1
        environment:
          - cluster.name=docker-cluster
          - bootstrap.memory_lock=true
          - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
        ulimits:
          memlock:
            soft: -1
            hard: -1
        mem_limit: 1g
        volumes:
          - esdata1:/usr/share/elasticsearch/data
        ports:
          - 9200:9200
        networks:
          - esnet
      elasticsearch2:
        image: docker.elastic.co/elasticsearch/elasticsearch:5.6.3
        environment:
          - cluster.name=docker-cluster
          - bootstrap.memory_lock=true
          - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
          - "discovery.zen.ping.unicast.hosts=elasticsearch1"
        ulimits:
          memlock:
            soft: -1
            hard: -1
        mem_limit: 1g
        volumes:
          - esdata2:/usr/share/elasticsearch/data
        networks:
          - esnet
    
    volumes:
      esdata1:
        driver: local
      esdata2:
        driver: local
    
    networks:
      esnet:
    

    However, it doesn't explain how to customize the password. It does direct us to a X-Pack documentation page, but I refuse to believe I have to go through all that trouble just to change a password. Is there any simpler, canonical way of configuring a custom password for elasticsearch on a Docker Compose file?

    Did they delete it? Because I don't see this variable in the new docs for 6.x? elastic.co/guide/en/elasticsearch/reference/6.x/docker.html

    Just FYI, I've confirmed that setting the env variable ELASTIC_PASSWORD works in elasticsearch:7.9.1

    It looks like ELASTIC_PASSWORD variable is supported only in platinum version of the docker image: elastic.co/guide/en/elasticsearch/reference/6.1/…
